雷射都卜勒血流監測儀
產品型號:
廠牌名稱: Oxford Optronix
Oxford-Optronix 使用雷射都卜勒原理根據血流監測（LDPM）最尖端的技術，提供堅持可靠、耐用和靈敏度無與倫比的標準。
可偵測局部區域的相對血流數據。
產品特點
血液的流動，可以提供組織中重要的氧氣和營養物質，同時帶走廢物和傳遞生物組織因子和分子訊號。微血管血液流動測量為研究人員提供了許多研究應用中的血液供應改變的關鍵訊息。
- 最新ART(Artifact Rejection Technology)技術，可以有效過濾干擾訊號
- 全自動探頭辨識系統，可自動導入校正值，即插即用
- 多頻道系統，可以讓您同時對不同的位置進行血流偵測
- 全新觸控式螢幕，不但可以以數值方式呈現即時數據，也可以用圖形化顯示
- 2年原廠保固
